Maximum polyp diameter1, mm	6 (5.0-10.0)	6 (5.0-7.0)	< 0.001
Hemorrhoid treatment modality			0.106
RBL	43 (43.0)	194 (34.6)
EPFS	57 (57.0)	367 (65.4)
Intravenous anesthesia	88 (88.0)	531 (94.7)	0.012
Hemorrhoid procedure time, minutes	10.4 (8.5-13.6)	10.2 (8.1-13.1)	0.618
Total operation duration, minutes	32.1 (22.9-40.1)	25.2 (20.3-32.0)	< 0.001

¹Analyses were limited to patients who underwent concomitant polypectomy (≥ 65 years, n = 88; < 65 years, n = 412).

P values were calculated using the Pearson χ² test, Fisher’s exact test, the Fisher-Freeman-Halton exact test, or the Mann-Whitney U test, as appropriate. RBL: Rubber band ligation; EPFS: Endoscopic polidocanol foam sclerotherapy.
